Rust

The Intel Core i5-12600KF paired with the NVIDIA GeForce RTX 3070 Ti delivers a highly playable Rust experience across most resolutions, but the data reveals a clear shift in system bottleneck as pixel count rises. At 1920x1080, the configuration is firmly CPU-bound in lower presets, while at 3840x2160, the GPU becomes the dominant limiting factor. The measured frame rates show a predictable scaling pattern: dropping from Low to Ultra at any given resolution imposes a significant performance penalty, with the gap widening as resolution increases. Across all twelve measured data points, the combination ranks 646th out of 1717 tested combos, placing it in the upper third of all systems. This mid-tier ranking is consistent with the hardware’s individual standings—the CPU sits in the 84th percentile of all processors, while the GPU ranks in the 74th percentile of all graphics cards.

Resolution Scaling

The frame rate drop from 1080p to 4K is substantial and reveals where the performance ceiling lies. At Low settings, the system delivers 193.6 FPS at 1920x1080, but this falls to 134.9 FPS at 2560x1440—a 30.3% reduction—and then to 80.8 FPS at 3840x2160, which is a 58.3% drop from the 1080p figure. This steep decline at higher resolutions indicates that the RTX 3070 Ti’s rendering throughput becomes the primary constraint once pixel count rises. The GPU’s 8 GB of GDDR6X memory and 608.3 GB/s bandwidth are sufficient for Rust’s demands, but the 21.75 TFLOPS of FP32 compute is taxed heavily at 4K.

At Ultra settings, the scaling is even more pronounced. The system achieves 82.3 FPS at 1080p, which drops to 58.6 FPS at 1440p (a 28.8% decrease) and then plummets to 32.7 FPS at 4K—a 60.2% reduction from the 1080p baseline. The fact that the 1080p-to-1440p drop is relatively modest compared to the 1440p-to-4K drop suggests that the CPU can still keep pace at 1440p, but the GPU is overwhelmed at 4K. This pattern is consistent across all settings: the percentage loss from 1440p to 4K is consistently larger than the loss from 1080p to 1440p. For example, at Medium settings, the drop from 1440p (88.4 FPS) to 4K (52.6 FPS) is 40.5%, while the drop from 1080p (129.4 FPS) to 1440p is 31.7%. The data clearly shows a GPU-bound scenario at 4K, while 1080p and 1440p benefit from the CPU’s strong multi-core performance.

Settings Recommendations

The measured rows provide a clear picture of the optimal settings for different refresh rates and resolutions. At 1920x1080, High settings deliver 113.2 FPS, which is suitable for high-refresh-rate monitors, while Medium pushes to 129.4 FPS for those seeking even higher frame rates. Low settings at 1080p yield 193.6 FPS, but this comes at the cost of visual fidelity that most players would find unnecessary given the High preset’s playability. For 2560x1440, High settings at 77.8 FPS offer the best balance, as Medium only improves to 88.4 FPS but the visual difference is marginal. At 3840x2160, the situation changes dramatically: High settings produce only 45.3 FPS, which is below the 60 FPS threshold for smooth gameplay. Medium at 4K drops to 52.6 FPS, still short of ideal, while Low at 80.8 FPS becomes the only viable option for playable 4K performance. Ultra settings are generally not recommended at any resolution above 1080p, as the 58.6 FPS at 1440p and 32.7 FPS at 4K fail to provide a consistent experience. The data suggests that High is the sweet spot for 1080p and 1440p, while Low is the practical ceiling for 4K.

GPU Role

The NVIDIA GeForce RTX 3070 Ti plays a decisive role in Rust’s higher-resolution performance. Its 8 GB of GDDR6X memory on a 256-bit bus provides 608.3 GB/s of bandwidth, which is ample for Rust’s texture streaming demands. The GPU’s boost clock of 1770 MHz, combined with 6144 shading units and 192 texture mapping units, drives the frame rates seen in the 4K tests. At 3840x2160, the GPU’s compute throughput of 21.75 TFLOPS becomes the binding constraint, as evidenced by the large performance gap between Low (80.8 FPS) and Ultra (32.7 FPS). This 59.5% reduction from Low to Ultra at 4K dwarfs the 57.5% reduction at 1080p (193.6 FPS to 82.3 FPS), indicating that the GPU’s pixel and texture fill rates are more heavily taxed at higher resolutions. The GPU’s 169.9 GPixel/s pixel rate and 339.8 GTexel/s texture rate are sufficient for 1080p and 1440p, but they fall short of sustaining 60 FPS at 4K with high-quality settings. The GPU’s benchmark scores reinforce this: its Passmark G3D score of 23356 and 3DMark Steel Nomad score of 3478 place it in the 74th percentile of all GPUs, with nearest rivals including the AMD Radeon RX 6700 (0.8% ahead) and the AMD Radeon RX 590 GME (0.3% behind). These close margins suggest that the RTX 3070 Ti’s performance is well-established, and Rust’s 4K demands exceed its capabilities for high presets.

Measured FPS Breakdown

At 1920x1080, the system delivers a wide range of frame rates depending on settings. Low settings produce 193.6 FPS, which drops to 129.4 FPS at Medium, 113.2 FPS at High, and 82.3 FPS at Ultra. The step from Low to Medium is the largest single-preset drop at 33.2%, while the Medium-to-High reduction is a more modest 12.5%. The High-to-Ultra drop is 27.3%, showing that Ultra’s additional effects impose a heavy cost. At 2560x1440, the pattern shifts: Low yields 134.9 FPS, Medium 88.4 FPS, High 77.8 FPS, and Ultra 58.6 FPS. Here, the Low-to-Medium drop is 34.5%, while the Medium-to-High drop is 12.0%, and the High-to-Ultra drop is 24.7%. The 1440p results show a more compressed range, with the Low-to-Ultra gap being 56.6% compared to 57.5% at 1080p. At 3840x2160, the frame rates compress further: Low achieves 80.8 FPS, Medium 52.6 FPS, High 45.3 FPS, and Ultra 32.7 FPS. The Low-to-Medium drop is 34.9%, Medium-to-High is 13.9%, and High-to-Ultra is 27.8%. Notably, the 4K Ultra result of 32.7 FPS is the lowest measured value across all twelve data points, while the 1080p Low result of 193.6 FPS is the highest. The data shows that the system can comfortably exceed 60 FPS at 1080p and 1440p on all but the Ultra preset, but at 4K, only Low settings break the 60 FPS barrier.

CPU Role

The Intel Core i5-12600KF provides the computational foundation for Rust’s simulation and physics. With 10 cores and 16 threads based on Alder Lake architecture, the CPU’s multi-threaded throughput is substantial, as reflected in its Cinebench R23 multi-core score of 23,444 and Passmark multithread score of 27,575. The CPU’s base clock of 3.70 GHz and boost clock of 4.90 GHz ensure that single-threaded tasks, such as Rust’s game logic and draw call processing, are handled swiftly. The 3DMark single-thread score of 1016 and Cinebench R23 single-core score of 3309 confirm strong per-core performance. The CPU’s 20 MB of shared L3 cache and 1.25 MB per-core L2 cache provide ample fast storage for frequently accessed data, reducing latency in complex scenes.

The CPU’s impact on Rust’s frame rates is most evident at lower resolutions and settings. At 1080p Low, the 193.6 FPS result is likely CPU-limited, as the GPU is not fully saturated at such a low preset. The transition to 1440p Low (134.9 FPS) and 4K Low (80.8 FPS) shows the GPU taking over as the primary constraint. The CPU’s nearest rivals include the Intel Core i9-10900K, which scores 27,829 on average (0% delta), and the Intel Core i5-12600K, which scores 27,851 (-0.1% delta). The Core i5-12600KF’s average benchmark score of 27,827 places it at the 84th percentile of all CPUs, indicating that it is a capable processor for gaming workloads. The CPU’s 125 W TDP and Intel Socket 1700 compatibility make it a straightforward fit for mainstream builds, and its unlocked multiplier allows for overclocking headroom, though the measured data reflects stock performance. In Rust, the CPU’s 10 cores and 16 threads are well-utilized during base building and large-scale raids, where the simulation of numerous entities can become a bottleneck. The benchmark results show that at 1440p and below, the CPU can feed the RTX 3070 Ti adequately, but at 4K, the GPU’s limitations are exposed, confirming that the CPU is not the primary limiting factor at higher resolutions.
